Golf tees used for playing on a golf mat.
Tees are very durable and are flexible so will last a while without worry of breaking or damaging your golf club. Included are the most common heights for driver off the tee without having to stick a tee into the golf mat. The base is wide enough that they balance very well on a golf mat, while the tee angles up to the top to avoid your club hitting the tee before the ball. 
Would work well with Skytrak, Mevo plus, Garmin R10, Uneekor, Rapsodo, or any other golf simulator or launch monitor
Sizes included

4- 1.25 inch
4- 1 inch
4 -.16 inch

This is my newest version of tee which in testing lasts longer than previous versions

Dark blue or black recommended for camera based systems. Light colors May confuse camera based systems.

Tees become hard and inflexible in cold weather causing them to break much sooner. Recommended to use above 60 degrees Fahrenheit.
